Marcus Miller M2 5 TBL 2nd Gen

So i bought this bass in the middle of 2023 and i was pretty happy with it. Did a sound test, played all the frets to check for action and buzzing and all that, and it was alright except the high B string had a rattling between the 5th and 6th fret which was fine with me, its a fixable thing. Boy was i wrong. Came out, the neck had a dip on the high G and B string from the first to 5th fret and this year just two months ago i noticed that the neck has developed a really strong warp while all my other guitars are dead flat and fine. So, after a long time of procrastination i decided to try adjust the truss rod and essentially its dead in a ditch because of course it is so to the garbage it goes. Shame, really.

I wanted to say i love the tuners but i forgot i upgraded them to Gotoh GB-350-5 since a few of them broke at the same time during tuning.
